Q: I have Windows Server "8" Beta volumes de-duplicated. Can I just install the Release Candidate and still access my data?

A: Yes, the deduplication is compatible between the beta and release candidate. Just remember you must install the Data Deduplication role service, which is available under File And Storage Services\File and iSCSI Services. After you install the Data Deduplication role service, the deduplicated data will be available.
